Be it known that I, AUeUsTu citizen of the 7' at 1 Rue Saint-Claude, Paris, public of France, certain new i Device for Vats, of which the following is a specification.

his invention-relates to improvements in devices which are used for the purpose of drawing oif liquids under pressure withoutbringing them in contact with the air, such devices being more particularly applicable T is invention relates to a device of this kind more particularly for th fitting to t e l t ese members being adapted to retain the part of the solid substances which might be found in suspension in the liquid to be racked, such stopper being at the same time adapted to be screwed alternately to the inlet member to the inner end of the tubular bung.

he accompanying drawings show by way of example a vertical section of the racking evice according to this invention. In such drawings, is designates the tubua-r bung secured in the aperture of the vat or other container of the liquid to be racked. Slidable in such bung is the draft tube 6, the joint around the said tube being made rubber washer w screwed into the outer end of the bung, or by any other suitable watertight arrangement.

e inner end of the bung 7c is threaded at the outside of its periphery at s. inner end of the tube drical inlet member a the diameter of which is not greater than that the bottom of which carries anextension u and :mall tubes 0 which extend downward with n the member, their inner orifices being VATS.

located at some of the said memb boss 4) which threaded internally for the purpose of being screwed onto the extension 24 of the inlet A washer r of rubher or other suitable material is placed on around the boss 1). As the inner diameter of the cup is of the inlet formed bestances, some of the latter will be sent bottom of the cup tion of the same against the wall of the tube near the orifice p, and other small solid sub stances, which may ave passed through the small tubes 0, will fall to the bottom of the inlet member a. So the liquid is rid almost completely of the solid substances in suspension.

The drawing oif being done, will i In he extension u and the cup-shaped stopper will be unbe e and the inlet member a can be taken entirely out.

Iaving thus described my invention, I claim as new and desire to secure by Letters atent:

1. The combination ing an inlet member at its inner end, and a cup-shaped stopper the inner diameter of which is greater than the outer diameter of the said inlet member, such cup-shaped having its inner end threaded at its periphstopper being adapted to be secured. by ery, a draft tube adapted to pass through screwing to the bottom of the inlet member said bung and having an inlet member at its 20 in thus forming an annular chamber around inner end, and. a cup-shaped stopper to be 5 such member, substantially as described and secured by screwing to the bottom of the for the purpose specified. inlet member in thus forming around such 2. A draft tubehaving an inlet member member an annular chamber, and the inner at its lower end, the orifices of such memwall of the said cup-shaped stopper being 25 her having tubular prolongations extending threaded for the purpose of being screwed 10 downwardly into the interior. onto the said end of the tubular bung.

8. The combination of a draft tube the In testimony,that I claim the foregoing inner end of which is provided with openas my invention Ihave signed my name in ings, and has a threaded prolongation and of presence of two subscribing witnesses.
